Hi all, we're preparing for the switch to lead free and I was wondering how dangerous/harmful to our new wave oven it would be to run tin lead parts through the no lead wave. Will the lead build up and cause issues?

Yeah, adopting is the right word. In this new lead-free era spec.'s are made to stay within the scoop of the RoHS directive. The driving force for spec.'s should be reliability. Did you see any impurity level spec.'s yet in wave soldering for Cu, Au, Ni, Zn, Fe etc. in lead-free, or are these impurities not important anymore? These metals are dissolving about a 100 times faster in lead free compared to leaded alloys. The European government with the help of sales people does an excellent job in brainwashing and makes us believe we have been chasing ghosts for the last 30 years. A minority can only rule when creating chaos and confusion and this is exactly what is going on with lead-free.

Just wanted to state some facts, because no clear answer is available in lead-free "yet"
